The James Webb Space Telescope observed a planet-forming disk with unexpectedly low water and high CO2 content, challenging existing models.

Data from JWST revealed the disk around a young star lacks typical water vapor but has elevated carbon dioxide levels. This suggests alternative planet formation processes in certain stellar environments. Astronomers analyzed infrared spectra to confirm findings. The discovery prompts revisions to protoplanetary disk theories.

Significance

• Impacts understanding of exoplanet atmospheres.
• May explain carbon-rich planets.

Further observations are scheduled.
